The Problem: Gemini Keys Leak + Google IAM Slows You Down
Google AI Studio keys and project-level access are valuable. Calling Gemini directly from React, Next.js, Angular, or Vanilla JS can expose your key through DevTools, build artifacts, or network logs.
Environment variables do NOT secure frontend builds. Serverless still means secrets + CORS + deployment pipelines.
On top of that, Google Cloud IAM and project configuration can slow down fast-moving teams. If you just want to ship, the setup becomes the Backend Tax.
What Happens When Your Gemini Key Leaks?
- Unauthorized usage that burns quota
- Unexpected billing spikes
- Abuse from scraped keys
- Downtime when you hit limits
The Solution: The Salting Layer
Instead of calling Gemini directly, you call your secure bridge:https://api.salting.io/r/salting-io-bridge-uuid
Your real Gemini key stays encrypted inside Salting. We handle:
- Secret key vaulting
- AES-256 request encryption
- CORS enforcement
- IP & rate limiting
- Abuse protection
- Header handling (e.g.,
x-goog-api-key) server-side
You get backend-level security without running a backend.
How It Works
- Add your Google AI Studio key to your Salting dashboard.
- Generate a private Bridge URL.
- (Optional) Lock usage to your domain.
- Replace your client-side requests with the bridge URL.
- Deploy instantly.
No proxy server. No IAM rabbit hole. No CORS debugging.
Salting vs Traditional Backend Setup
🚧 Traditional Backend Proxy
- Requires Node.js / Go server
- Manual CORS configuration
- Secret key stored in your infrastructure
- Custom rate limiting implementation
- Ongoing maintenance + monitoring
- Extra deployment complexity
☁ Serverless Function
- Cold starts possible
- CORS handling still required
- Secrets + deployment pipeline complexity
- Scaling cost spikes under load
- Still infrastructure to maintain
⚡ Salting Layer (Recommended)
- No server required
- Encrypted key vault
- Built-in CORS enforcement
- Integrated rate limiting
- Abuse protection by default
- Deploy in under 2 minutes
What Can You Build?
- Fast chat assistants
- Research & summarization tools
- Multimodal apps (text + image workflows)
- Internal copilots
- AI dashboards
Perfect for Angular, React, Next.js, Vue, static sites, and serverless apps.
Frequently Asked Questions
Does Salting work with Gemini models like Pro/Flash?
Yes. Salting forwards requests transparently.
Is Salting a proxy?
Technically yes — but optimized for security, speed, and zero infrastructure management.
Does this replace my backend?
If your backend exists mainly to hide keys and control usage, yes.
Can I lock usage to my domain?
Yes. Use domain locking + CORS enforcement to prevent unauthorized origins.
Does Salting add latency?
Minimal edge overhead (typically sub-30ms).
Stop Exposing Your Gemini Key
If your frontend can see your Gemini key, attackers can too. Secure it in minutes and ship confidently.
